Just to clarify, when you say "shutdowns of all their flash services" this means they shut down their distribution system that was for distributing your game to portals automatically as well as one other service. They didn't shut down the flash game marketplace or stop all flash-related activities.
Ads (FGL Ads, announced shutdown in a separate post 1 or 2 weeks ago, follows the shutdown ~a year ago of the former largest ad company in this space Mochimedia), in-game services (Gamersafe leaderboards, achievements etc), and distribution (Flash Game Distribution). The marketplace is the only thing staying up although it's massively declined too and now has 0 people working on it after layoffs a few weeks ago.
You're right in illustrating how things are winding down - I just wanted to point out it wasn't a complete shutdown of all things Flash. Ads were never as big a component of the flash game industry they are in mobile apps: sponsorship and mtx were the kings.
